Novel Noise Injection Scheme to Guarantee Zero Secrecy Outage under Imperfect CSI [PDF]

open access: yesEntropy, 2023
The paper proposes a novel artificial noise (AN) injection strategy in multiple-input single-output multiple-antenna-eavesdropper (MISOME) systems under imperfect channel estimation at the legitimate channel to achieve zero secrecy outage probability ...

Secrecy Performance of Cooperative Cognitive Radio Networks Under Joint Secrecy Outage and Primary User Interference Constraints

open access: yesIEEE Access, 2020
In this paper, we investigate the secrecy performance of a Cooperative Cognitive Radio Network (CCRN) in the presence of an eavesdropper (EAV). The secondary users (SUs) are subject to three constraints which include peak transmit power level and ...

Secrecy outage probability analysis for RIS‐assisted NOMA systems [PDF]

open access: yesElectronics Letters, 2020
In this Letter, the physical layer security for a novel reconfigurable intelligent surface (RIS)‐assisted non‐orthogonal multiple access (NOMA) system in a multi‐user scenario is investigated, where the authors consider the worst case that the eavesdropper also utilises the advantage of the RISs.

On secrecy outage probability for downlink NOMA systems with relay–antenna selection [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2021
AbstractSecure transmission is essential for future non-orthogonal multiple access (NOMA) system. This paper investigates relay–antenna selection to enhance physical-layer security of cooperative NOMA system in the presence of an eavesdropper, where multiple antennas are deployed at the relays, the users, and the eavesdropper.
